CHANGEABLE EXHVIBTOR.

- Application led October 16, i926. Serial No. 142,024.

The invention relates to' changeable eX- hibitors, and has as an object the provision of a. device of this nature which, by means of a reciprocating part, shifts the exhibited card from a 'lower to an upper position, and upon the return of the reciprocating part shifts a card from an upper to a lower posi-l tion.

An object of the invention is to provide a device that will .successively exhibit each card of a series in rotation.

A further object of the invention is the provision of a changeable exhibitor which may be used as a calendar to exhibit in turn the numbers of the days of the month, or which may be used to likewise exhibit a plurality of advertising cards.

A further object of the invention is the provision of a device of the character de-V scribed having means to prevent the reversal of movement of the reciprocating part until after a full stroke thereof has been made.

A further object of the invention is the provision of device oi this character in which the cards are held in position for shifting during movements of the reciprocating part.

rA further object of the invention is the provision of a device of this character of exceedingly simple mechanism. v

Fig. l0 is a detail perspective view of the frame of the device;

Fig. ll is a detail perspective view of the lreciprocating member, and

Fig. 12 is a detail perspective view of one of the card holding clips.

As shown in Fig. l, the device comprises a base 2O and a casing 21, shown in a desirable form for acalendar. As shown in this iigure, there is an opening 22 through the casing wherein the exhibited card may be viewed, and a pocket 22 in which a pack of slips may be inserted, having an opening 23 in its front through which the outer slip may he viewed. 1When used as a calendar, it is to be understood that the package of slips may contain aslip for each month of the year, which'slip may be removed and the desired month brought to the outside of the pack, after which the slips may be reinserted in the pocket.

`rlhe card holding and shifting mechanism comprises a frame 24, shown in perspective view in Fig. 10, and comprising uprights 25, 26, in spaced relation, and is held by transverse members 27, 28, 29, between which members the cards to be exhibited may be contained, one-halt in each space, a card being shifted Jfrom the lower to the upper space upon the upward movement of the reciprocating member, and a card from the other side'oi1 the pack may be shifted from the upper to the lower space upon' return of the reciprocating member. K

The frame 24; further comprises a pair of ears 30, 3l, for support of the frame upon the base 2O in the manner disclosed in Fig. 2.

As shown, the casing 21 has inturned ears 32, 33, overlying the base 20, and which may be secured thereto by means of screws 34; insertable from below. The casing 21 further comprises upper inturned ears 35, 36 adapted to project inwardly into contact with the upper end of the tops of the members 25, 26

orp the frame 24, and a cap 37 may be secured frame made up of side plates 44, 45 and end plates 46, 47, the plate 44 having projecting ears 48, 49 at its lower end and ears 50, 5l at its upper end. The plate 45 is formed eX actly as is plate 44 in inverted position.

To engage the edges of cards and shift the same the ears 48, 49 are shown as folded upon themselves to provide portions 52, 53 projecting into the plane of the cards to move the card upwardly as the frame rises, the plate -45 having like portions 54, 55 to engage the upper edge of the card upon the nos dll

Vreverse side of the frame to shift the card downwardly in the downward movement of the frame. To produce movement of the frame there is shown a button 56 projecting/through a slot 57 in the rear of the easing, and having screw threaded engagement with a boss 58 carried by the rear plate 45.` The button'56 may be removed in the dismantling of the casing from-the mechanism.

To provide continuous pressure. to the rear, upon the upper-cards', there are shown a'pair of fingers 59, 60 pivoted upon a rod 6l, passing through the openings in the lugs 40, 41` thereV being coil springs 62, 63 anchored upon the rod 6l and having projecting ends 64, pressing against the integral lugs 66, 67 projecting from the lingers 59, 60. At the bottomofthe rear of the device lingers 68, 69 are pivoted upon a rod 70mounted in the lugs `42, springs 7l, 72 acting in the salme manner as springs 62, 63.`

Y The lingers `59, 60 Vand their voperating mechanism are duplicates of the springs 68, 69, and the latter operating to press the lower pack of cards forward in exactly the same manner as the upper fingers press the upper cards rearwardly. i

As the frame 45 is forced upward the shorter finger 68 will first raise over the narrowed portion 73 of the `plate 45. At this time the finger 69 will still be in contact with the rear card of thelower pack to press the pack forward, and when the narrowed portion 73 of the platei 45 has passed the lower finger it will return to contact with the card and the narrowed portion 73 will then pass under thefinger `69 whereby the card will at all times have the pressure of at least Tone of the fingers and maintain the pressure forward ofthe cards in the pack. In `its upward movement, the `frame will first pass under the spring 60 by virtue of V43, there being the cam surface 74, the short upper spring 59 at this time preserving the pressure rearwardly upon the upper pack, and when the narrowed portion 75 of the plate 44 'has passed the long linger 60 itV willreturn into contact with the card, after which the short finger 59 will be lifted by the package thereunder of the narrowed portion 75. I

The side members 25, 26 are of the saine thickness as the thickness of the pack of cards in the A upper or lower space. The pack has one more card below than above duringthe normal position of the` device, and `one more card in the upper space at the limit of upward movement of the` sliding frame. Thecross members 27-28-29 are of' a width sufficient to stand the thickness of a card inward from the edges ofthe upright members 25, 26 at both `front and rear edges of these members to permit ofthe passage-.oitl the card within the width of the uprights 25-26. i Y

To hold tliecards in the space between l the cross members 27-29, during movement ofthe reciprocating member, there are shown clips 76--76, normally lying in contact one with the upper surface of the member 29, `and the other in contact with the lower surface of the member 27, having ears 77-78, projecting downwardly lapping'the surfaces of the cards, as clearly shown in Fig. 6, whereby the cards areV retained in the space between the `transverse members and against the pressure of the fingers 59, 60, and 68u69. Alhe .clips 76` are desirably pivoted upon the members 27, 29 by means ofears,79,`80, adapted to `project downwardly into openings 8l, 82 in said members, and the clips are pressed toward the surface ofthe members by means of a spring83 atthetop, and a spring 84 at thebottom anchored to the inner surface ofthe members 25, 26, as shown at 85, 86.'

ln the `normal position of the device shown in Figs. 2, 3 and 6, the portions 52, 53 of the side plates underlie the lower edge of the'outside card, t-he clip '76 at the bottom being then depressed, as shown in Fig. 2, by contact with the edge of' the plate 44 at its reduced portion 87. Then the frame'45 is,

raised the upper clip 76i`slifted in exactly the "same clip is thus raised out oi clipping contact with the card the pressure of the spring fingers59, 60er 68, 69 will force the card toward the opposite side over the members` 52,. 53 or'54, 55. The subsequent'reciprocation of the frame`45 then shifting the card either upwardly or downwardly, in Yaccord-i ance with its direction of motion.

To prevent a partial stroke of the reciprocating frame 45 whereby a card might b e raised part way and the reciprocatingmember then be lowered to permit the feed of a manner. `When the upper or lower.`

subsequent card, therev is shown a serrated plate 88, shown as carried by the interior surface of the rear wall of the casing, and aV trigger 89 is pivoted upon the boss 58, which trigger has a linger 90 held in the position shown in F ig. et, by means of a spring 91 acting in tension, anchored as at 92. As the trigger S9 is carried upwardly, the finger 9() wipes over the serrations of the plate 8S, assuming the diagonal position shown in 89, which effectually prevents downward movement of frame l5 until the frame has been carried to the top of its stroke allowing the trigger to pass the upper serrations of the plate 88, at which point the normal position of AFig. 4l is resumed. rlhe upward stroke of the plate is then complete, and upon its downward stroke the trigger' 89 assumes a reverse diagonal position effectually preventingreturn upward of the frame L.t5 until the downward stroke of the frame has been completed.

To cover the slot 57 in the rear of the casing, there is shown a plate 93 pivoted to the interior of the casing, as at 9a, and spring pressed to the position shown in Fig. 9 by means of a spring 95 anchored at 96 to the casing. Upward movement of the bess 58 acting against the cam surface 9T will vstretch the spring 95 to allow passage of t-he boss, the plate 93 passing through the dotted line position in F ig. 9 and returning to the position, covering the slot upon the subsequent downward stroke of the boss 58.

It will be seen that the mechanism is duplicated at the two ends of the frame 25, and that with the exception of the presence of the boss 58 the frame 45 might be reversed in its position upon the frame 25 and be fully operable. Thile the frame is shown as arranged vertically, it is obvious that since the attraction of gravity upon the cards has no function, the frame can be arranged horizontally without necessary changes in mechanism. rlhe frame l5 may be reciprocated in any desired manner, and the device may be used not only as a calendar, but in an enlarged size for advertising display of cards. The operation of the device will be clear from the above description.

Minor changes may be made in the physical embodiment of the invention without departing from the spirit thereof within the scope of the appended claims.
